So I also tested the ACPI boot. I will formally submit the QEMU series ASAP.

Implement the virtio-iommu driver, following specification v0.12 [1]. Since last version [2] we've worked on improving the specification, which resulted in the following changes to the interface: * Remove the EXEC flag. * Add feature bit for the MMIO flag. * Change domain_bits to domain_range. Given that there were small changes to patch 5/7, I removed the review and test tags. Please find the code at [3].
